DUMIPING BUTTER-MOLD.

Patented June 10, 1919.

Application filed June 28, 1918. Serial No. 242,379.

To all whom it may concern Be it known that I, RUFUS A. SIMPSON, a

. Molds, of which the'following is a specification.

The present invention relates to improvements'in receptacles for containing butter, generally known as dumping butter molds, and the sides of which can be readily spread for the purpose of discharging its contents.

' The object of the invention is to provide a dumping mold of this character in which the means for securing together the sides, while permitting them tobe readily spread apart, when desired, wi l be simple, inexpensive, and convenient in use.

In the accompanying drawing, Figure 1 is a perspective view of my improved dumping butter mold; Fig. 2 is a broken plan View showing a single corner thereof; Fig. 3 is a similar view of the corner when the butter mold is opened or spread Fig. 4 is a vertical section on the line 4-4 of Fig. 2; Fig. 5 is a similar section on the line 55 of Fig. 8; Fig. 6 is a plan view of another corner thereof; Fig. 7 is a plan View of the latter corner when the butter mold is opened or spread; Fig. Sis a vertical section on the line 88 of Fig. 6; Fig. 9 is a vertical section on the ine 99 of Fig. 7.

Referring to the drawing, 1 indicates a bottom of a mold,-all the edges 2 of which flare upwardly. Surrounding said bottom are vertically extending side boards 3 and end boards 4, all boards beingpreferably spaced apart about one-eighth of an inch to allow for. swelling. The bottoms of the boards3, 4, are secured to the bottom 1 of the mold by side cleats 6 and end cleats 7 through which, and through the bottoms of the boards 3, 4, and into the board 1, are screwed screws 8, thus firm y securing the lower ends of the side and end boards to the bottom of the mold. The tops of the boards are rabbeted, as shown at 9, to connect thereto top bars 10, 11, which are also connected to the tops of the boards by dowel pins 12 driven through said boards into the inner portions of said top bars. The end boards 4 extend higher than the side boards 3 and in like manner the central portions of the end bars 11 extend higher than the side bars 10. The terminal portions 13 of the ends bars are recessed, as shown at 14, to re ceive the ends of the side bars, the bottoms of said recesses being at their inner portion 16, parallel with the outer sides of the end bars, but the outer portions 17 of said bottoms extending oblique thereto, at an angle of about I 55 therewith, the outer portions of the ends of the side bars being also oblique tofit closely against the outer portions of the bottoms of the recesses in the end bars.

. The end and side bars are so secured to the bottom of the mo d that, when their upper ends are free, they extend slightly outward from the vertical. But they are made suiiiciently thin to permit them to be bent inward, and they can be brought to a vertical position by means of metal tightener rods 18 which extend longitudinally of the mold and of each of which one end is hook-shaped, as shown at 19, the main portion thereof extending through a transverse hole 21 through the adjacent end bar, while the hook-shaped portion 19- extends from the outer side of said end bar intoa recess 22 therein opening at its outer side. The other end of the rod is threaded and is passed through a transverse hole in the other end bar and then through a circular tightener 24 having on its opposite edges crown cams 26 each extending through nearly one-half of its circumference, and finger pieces 27 at the ends of said crown cams.

A wing nut 31 is screwed on the threaded end of the tightener rod, the tightener 24 turning with the wing nut on the rod whi e the wing portions 32 of said nut rest in depression 35 in the higher ends of the crown cams. The end and side bars are then looked together in their innermost positions. Lock nuts 33 are then screwed on the threaded ends of said rods until they abut against the o'utersidesof the wing nuts. The tightener is then turned in the same direction as the wing nuts were turned so as to cause the wing portions of sald nuts to rest upon the lower portions of said cams, thereby permitting the tighteners to move outwardly upon the rods and the tops of the end bars to spring outwardly to the same extent, the tops of the side bars then also springing outwardly. The mold is then ready to be packed with butter. In diagonally opposite corners thereof, close to the bottom, are small holes 34 leading through the adjacent side boards, to permit air to escape while the butter is being pressed into the dumping mo d and to prevent a vacuum being formed when dumping the butter. lVhen a sufficient amount of butter has been pressed thereinto, the tighteners 24 are turned in a left-handed direction, thereby forcing them inwardly on the rods, by reason of the wing nuts now engaging the higher portions of the cams, thereby also forcing inwardly the end boards and also the side boards, until the ends of the side boards fit snugly in the recesses therefor. v

To dump the butter the clamps are turned in a right-handed direction, whereupon the 7 ends and sides spring outward to an extent sufficient to permit the butter to be readily dumped.

I claim 1. A receptacle from which the contents are readily dumped, comprising a rectangular bottom, sides secured at their lower ends to said bottom, their upper ends being capable of moving inwardly and outwardly relative to each other, parallel clamping rods each extending through parallel sides and prevented'from moving from one of said sides toward the other, a device secured upon A each of said rods adjacent to the latter side, and a clamp rotatable around each rod and the rod, and a clamp around said rod between said nut and the latter side and having acam'portion engaging a wing of said nut to vary the position of said latter side with respect to said nut.

3. Areceptacle from which the contents are readily dumped, comprising a rectangularbottom, sides secured at their lower ends to said bottom, their upper ends being capable of moving inwardly and outwardly relative to each other, parallel clamping" rods each extending through parallel sides cent sidehaving a recess to receive the hookshaped end to prevent movement of the said rod from said side toward the other, the end of said rod adjacent to said latter side being threaded, a wing nut screwed on said threaded end, a lock nut screwed on said threaded end outside said wing nut,and a clamp around said rod between said wing nut and the latter side,said clamp nut having extending from opposite marginal, portions crown cams to engage the wings of said nut to vary the position of said clamp relative to said nut V i 4:. A receptacle from which the'con'tents are readily dumped, comprising a rectangular' bottom, sides secured at their lower ends to said bottom, their upper endslbeing capable of moving inwardly and outwardly relative to each other, parallel clamping rods each extending through parallel sides and prevented from moving from one of said sides toward the other, the end of said rod adjacent to the latter side being threaded, a

wing nut screwed on said threaded end of the rod,'and a clamp around said rod ber tween said nut and the latter side and hav ing a cam portion engaging a wingof said nut to vary the. position of said latter side with respect to said nut, said cam having in its highest portion a depression to retain the wing when received therein.

5. A receptacle from wh'ch the contents are readily dumped, comprising a rectangular bottom, sides secured at their lower ends to said bottom, their upper ends being ca-V pable of moving inwardly and outwardly relative to each other, and means for remov- 1 ably holding the upper ends of two parallel sides in their innermost position against-the outward pressure of the contents,said parallelsides and theother sides having at their adjacent edgesoblique surfaces co-engaging each other whereby the contractionof said parallel sides also contracts the othersides;
